Recent Developments and Challenges on Machining of Carbon Fiber Reinforced Polymer Composite Laminates

Abstract

In recent years, composites have attracted a great deal of interest because they lack the limitations of metallic and polymer materials. Although carbon-fiber- reinforced plastics (CFRPs) of the various composites exhibit superior properties, this machining has been challenging because the materials are anisotropic and non-homogeneous. The machining characteristics of CFRPs have been studied for over a decade. Recent studies have used advanced machining techniques to increase productivity and quality. Developments in sensing and computing technologies have been exploited to derive monitoring and diagnostic systems based on artificial intelligence. Although several reviews of CFRP machining have been published, they focused on predictive models or experimental studies on machining mechanisms and characteristics. Here, we review the current state-of-the-art research on advanced technologies and monitoring systems to guide future studies.
